Association of quality of prenatal care with contraceptive planning in a United States population: a retrospective cohort study

Abstract

BackgroundUnderstanding how prenatal care influences planned postpartum contraception can help guide shared decision-making. This study looks to examine the association of the quality of prenatal care with planned postpartum contraception.MethodsThis is a retrospective cohort study conducted in a single tertiary, academic urban institution in the southwest United States. The institutional review board (IRB) for human research at Valleywise Health Medical Center approved this study. Using a validated measure of prenatal care, the Kessner index, prenatal care was classified as adequate, intermediate, or inadequate. The World Health Organization (WHO) protocol for contraceptive effectiveness was used to classify contraceptives as very effective, effective, and less effective. The planned contraceptive choice was determined at the time of hospital discharge after delivery by discharge summary. Chi-squared testing and logistic regression were used to measure associations between the adequacy of prenatal care and contraceptive planning.ResultsThis study included 450 deliveries, 404 (90%) patients with adequate prenatal care, and 46 (10%) patients without adequate (intermediate or inadequate) prenatal care. There was not a statistically significant difference in planning for very effective or effective methods of contraception at hospital discharge between adequate (74%) and non-adequate (61%) prenatal care groups (p = 0.06). There was no association between the adequacy of prenatal care and the effectiveness of contraceptive planning after controlling for age and parity (aOR = 1.7, 95% CI 0.89–3.22).ConclusionsMany women chose very effective and effective methods of postpartum contraception; however, there was no statistically significant association between the quality of prenatal care and planned contraception at hospital discharge.
